National Party voters (78 per cent), those whose highest qualification was from high school (67 per cent) and those aged over 60 were particularly likely to say Anzac Day was the more meaningful occasion.
People with postgraduate qualifications (39 per cent), Green Party voters (39 per cent), Labour Party voters (34 per cent) and those aged under 30 (33 per cent) were relatively likely to say both days were equally important.
Green Party voters (21 per cent) and people with postgraduate qualifications (17 per cent) were by far the most likely to say Waitangi Day meant more to them than Anzac Day.
"The poll almost certainly reflects the ongoing tensions over Waitangi Day and how it should be acknowledged, with ANZAC Day being relatively uncontroversial,'' UMR research director Gavin White said.
Results were from questions included in the UMR Online Omnibus Survey conducted between March 28 and April 8, 2013.
The margin of error for a 50% figure at the 95% confidence level is +/- 3.1 per cent.
